Symptoms of coronary artery disease are most often located in the chest directly behind the sternum, but can also be located in the left precordial area, and in some patients can present as full chest pain. There may also be some areas of referred pain.
The most typical symptom of coronary artery disease is sudden chest pain, mostly located in the posterior sternum or precordial area, some patients can also be manifested as a full chest pain, without obvious boundaries, so any unexplained sudden chest pain may be caused by coronary artery disease, regardless of whether the left chest or right chest.
In addition to chest pain, patients with coronary artery disease may also experience referred pain in certain areas, such as the left upper abdomen, left shoulder, left upper limb, neck, jaw, etc. This is due to the fact that the afferent nerves of the above mentioned areas share common afferent pathways with the cardiac afferent nerves, therefore, unexplained pain in the above mentioned areas should be ruled out as a possible cause of coronary artery disease.
Patients with chest pain and suspected coronary artery disease are recommended to go to the hospital as soon as possible for timely improvement of tests such as electrocardiogram, echocardiogram, myocardial necrosis markers, etc., so as to make a clear diagnosis in time and then be treated accordingly.
